The German tech news site Heise Online reports that Knoppix 3.8 is being presented at CeBIT (Hall 9, Stand C39). Knoppix 3.8 has kernel 2.6 as default, KDE 3.3.2, OpenOffice 1.1.4, as well as... Firefox 1.0 and Thunderbird 1.0. There's also a really neato new thing involving unionfs . It seems to imply that you can change most anything on the running system, even as it is running from CD - and changes can be stored too (even on NTFS)
